Use the option that provides the balance criteria with the greatest variety in your configuration. For example,
if the traffic on a port channel is going only to a single MAC address and you use the destination MAC address
as the basis of port-channel load balancing, the port channel always chooses the same link in that port channel;
using source addresses or IP addresses might result in better load balancing.
The unicast and multicast traffic is load-balanced across port-channel links based on the configured
load-balancing algorithm shown in the show port-channel load-balancing command output.
